It is designed for chassis or panel mounting and handles wire from 12 to 22 AWG. The 0.315\" (8.00mm) pitch gives enough spacing for field wiring with a standard screwdriver, and the white polyamide housing carries a UL94 V-0 flammability rating. Typical use is as a power distribution point inside industrial control panels, HVAC equipment, or lighting fixtures where a compact, reliable screw-terminated strip is needed. The enclosed barrier prevents accidental shorting between adjacent terminals, and the steel screws with zinc finish resist corrosion in panel environments.","metaTitle":"Molex Eurostyle 391001803 Terminal Strip, 3 Circuits, 20 A, 600 V","metaDescription":"Molex Eurostyle 39100 391001803 terminal strip, 3 circuits, 0.315\" pitch, 20 A, 600 V, enclosed barrier, screw top, chassis/panel mount, 12-22 AWG, white, UL94 V-0, active.
